1 9/16" Shafts | McMaster-Carr

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into low-strength fasteners, pins, and axles. You can surface harden this material for added wear resistance. All have been manufactured to meet ASTM standards for quality and performance.

Cold-worked rods and discs have a finished look and quality. The cold-working process gives the steel consistent strength, hardness, and dimensions throughout.

Tight-Tolerance Easy-to-Machine W1 Tool Steel Rods

Yield Strength: 50,000 psi
Hardness: Rockwell B95 (Medium)
Heat Treatable: Yes
Max. Hardness After Heat Treatment: Rockwell C65
Fabrication: Hot Rolled
Specifications Met: ASTM A686

Made with lower amounts of alloy elements than other tool steels, these W1 rods are highly machinable. Also called drill rods, they are precision ground and held to strict diameter and straightness tolerances. They’re ready to be turned on a lathe. These rods are decarb-free, which means any surface flaws created during the manufacturing process have been removed. This makes them more machinable and leads to better results from heat treating or finishing. You can harden the surface with heat treating for added wear resistance or water harden for added strength. These rods are often used to make hammers, files, and reamers. All have been manufactured to meet ASTM A686 standards for quality and performance.
